I had sent myself 2 transaction for .0748458 and 1.1147815 from an exchange to my other wallet.The blockchain.info shows the transaction has been confirmed and then another transaction of the total amount being sent out.

https://blockchain.info/address/18EC8axfZZBj5rM3wfnVAZCPmuBP3v5E7r#I have checked my wallet BTC history and there is no deposit or withdrawal of the amounts missing. Could my wallet address been cloned to receive and then used again to send out? Which part could be compromised.... the person sending out the BTC or the bitcoin wallet receiving side?

Let me ask if the amount you send to your blockchain account still in your balance?If yes i think they automatically resend bitcoin to other bitcoin address but your account still had your balance. Its weird thing but i have a local wallet here which is the same happen to me if i send bitcoin to my bitcoin address its automatically send to other bitcoin address but in my wallet the bitcoin received still in my balance..

"If money was being invented now, it wouldn't be designed to look like cash or credit cards. It would look more like Bitcoin."

The exchange i sent from has processed the transaction and no balance.The wallet that was suppose to receive has not received them..

.0748458 and 1.1147815 has landed in 18EC8axfZZBj5rM3wfnVAZCPmuBP3v5E7rand it's being moved to another address as shown on this (unconfirmed yet) txid https://blockchain.info/tx/3c37c11bbf9e65b277bdda0925cbf8fb1b448ed977a395d93acee609a4546149what is your other wallet? web online wallet (no privkey control) or desktop wallet?if it is web wallet then 18EC8axfZ is your deposit address, so you have to contact your other wallet admin and ask him to fix crediting your balance

.0748458 and 1.1147815 has landed in 18EC8axfZZBj5rM3wfnVAZCPmuBP3v5E7r, I have checked this wallet and have no record of deposit. This wallet is at an exchange so its a web wallet.So, I should contact the wallet exchange admin for 18EC8axfZZBj5rM3wfnVAZCPmuBP3v5E7r?

i have checked on btc.com/18EC8axfZZBj5rM3wfnVAZCPmuBP3v5E7r The transaction of .07484 and 1.1147 have over 450 confirmations but they never reached my wallet and looking on the blockchain it shows the total of the transactions is being sent out from my wallet to another address. How is it possible if it never made it to my wallet?

Because that isn't YOUR wallet... it is an address belonging to an exchange... Effectively, what you have is simply a deposit address linked to an account. It is up to the service provider (ie. the Exchange) to then correctly credit your account with the value received to the deposit address. Note that this is not "actual" BTC. It is just a number in the Exchange's database... if the Exchange disappears tomorrow, so do your BTC.

Your ONLY option at the current point in time is to contact the Exchange that you sent the funds to and ask them why they have not credited your account. No-one here can help you.

Thank you for comment.Yes, I contacted the exchange and they said no coins deposited to the 'wallet', so i emailed them the blockchain.info and sure enough within the hour the coins were deposited.

I was thinking that does the exchange have a master wallet and when they see fit they will transfer them to their clients.

Again thank you for sharing your knowledge.

18EC8axfZ is actually your deposit address on an exchange? I thought you said from an exchange to your other walletwould you tell us what exchange is that? so that we can avoid using it I don't know how that exchange can keep up with user withdraw requests with that much BTC locked up in stuck unconfirmed transactions. in that address alone there are 2 unconfirmed outgoing transactions. for some reasons, the magic number 22 BTC being used multiple times for deposit amount to 1NzxprBES and 1B8fzVUto

Its Coinone in Korea.I noticed that my coins were received the same day that it was sent as I saw it on blockchain but as the price shot up, I didnt get a chance to sell them.Makes me think if the exchange were selling them.. and later crediting the clients.....
